I think I found the solution here:

@KauffK I think that you are partially right with your answer.
If there are 3 Scramblers and let’s say 3 Pings, the first Scrambler will take 10 stability from the first Ping, the second one 5 stability to finish off the first Ping and then the last Scrambler damages the second Ping.
I think this might be the solution, but I have to double check this first.
